To find the average net force exerted on the object, we can use the equation:

F = m * a

Where:

F = force

m = mass of the object (70kg)

a = acceleration

First, we need to find the acceleration of the object. We can use the equation:

s = ut + (1/2)at^2

Where:

s = distance traveled (1.6m)

u = initial velocity (0 m/s, as the object starts from rest)

t = time taken (1.2s)

Rearranging the equation to solve for acceleration:

1.6 = 0 + (1/2) * a * (1.2)^2

1.6 = 0 + 0.6a

a = 1.6 / 0.6

a = 2.67 m/s^2

Now, we can calculate the average net force exerted on the object:

F = 70kg * 2.67 m/s^2

F = 186.9 N

Therefore, the average net force exerted on the object is 186.9 Newtons.

- Length of barrel, L = 1.6m

- Mass of object, m = 70kg

- Time, t = 1.2s

- Average net force exerted on the object, F

The acceleration of the object can be calculated using the equation:

```

a = (v - u) / t

```

where:

- a is the acceleration

- v is the final velocity

- u is the initial velocity

- t is the time

Since the object starts from rest, u = 0. The final velocity can be calculated by using the equation:

```

v = L / t

```

Substituting the given values, we get:

```

v = 1.6m / 1.2s = 1.33m/s

```

Therefore, the acceleration of the object is:

```

a = (1.33m/s - 0) / 1.2s = 1.11m/s²

```

The net force exerted on the object is given by:

```

F = ma

```

Substituting the values of m and a, we get:

```

F = (70kg) - (1.11m/s²) = 77.7N

```
